Help with anniversary message at CR...

[Ladybugsy]

I need something to put on a banner at CR...I'm assuming when she says banner, she means with the diver. I'm not sure what to put on it, or how long it can be, etc. My aunt and uncle will be celebrating their 12th anniversary, and I have ordered them a cake as well. She suggested something like, "Morgan you made a great "catch"....but I kinda wanted the message to be from my family to them...although an undersea reference would be nice. Ideas? Thanks
